This is an observational cross-sectional study evaluating gait dynamics in
patients with Parkinson's Disease (PD) and severe postural deformities, PD
without axial deviations and healthy subjects. Ten PS individuals with Pisa
syndrome (PS) and nine subjects with Camptocormia (CC) performed 3-D Gait
Analysis and were evaluated with walking and balance scales. Correlations with
clinical and functional scales were investigated. Spatio-temporal and kinematic
data were compared to ten PD subjects without postural deformities (PP) and ten
healthy matched individuals (CG). Data obtained showed decreased walking
velocity, stride and step length in PP, PS and CC groups compared to controls.
The correlation analysis showed that stride and step length were associated with
reduced functional abilities and disease severity in PS and CC groups. Kinematic
data revealed marked reduction in range of movements (ROMs) at all
lower-extremity joints in PS group. While, in CC group the main differences were
pronounced in hip and knee joints. PS and CC groups presented a more pronounced
reduction in hip articular excursion compared to PP subjects, revealing an
increased hip flexion pattern during gait cycle. Moreover, the increased hip and
knee flexion pattern adversely affected functional performance during walking
tests. Results obtained provide evidence that step length, along with stride
length, can be proposed as simple and clear indicators of disease severity and
reduced functional abilities. The reduction of ROMs at hip joint represented an
important mechanism contributing to decreased walking velocity, balance
impairment and reduced gait performance in PD patients with postural deformities.
